Description

BMW E46 M3 S54 (01-06) Mishimoto aluminium fan shroud with electric fan

The Mishimoto fan shroud E46 M3 replaces the failure-prone mechanical clutch fan of the BMW E46 M3 with S54 engine with a slim 16 inch electric fan in a brushed aluminium shroud. The fan moves more than 1,850 cfm of air, over 3,100 m³ per hour, and comes pre-mounted on the shroud.

Because the engine no longer drives the clutch fan, Mishimoto measured up to 5 whp on the Dynojet between 6,500 and 7,500 rpm, and 1 to 2 whp across most of the rev range. The fan is mounted offset to leave room for popular supercharger kits.

Installation and delivery

Use the included tool to remove the clutch fan and the plastic parts of the original shroud, then mount the new shroud on the radiator. Mishimoto rates the installation as medium. The fan may require additional wiring; a fan controller is not included in this kit. The installation guide and engineering report are available below. Lead time: 4 to 7 days.

Clutch fan out, power in: an aluminium shroud with e-fan that keeps the S54 cool and frees up to 5 whp.

Why choose this Mishimoto fan shroud E46 M3?

The clutch fan of the E46 M3 costs power and is a known source of failures at high rpm. This aluminium shroud with electric fan solves both problems, also fits alongside a supercharger kit and looks clean in the engine bay. Mishimoto backs it with a lifetime warranty.
